Is there an easy way to delete images that are no longer required?

If you mean the images that you had uploaded to use on your form, then yes.

To do that, you would need to add the image field to your form. You can find it under Form Tools.

When you add it its wizard will get activated and all you would need to do is to click on Choose From Existing Images

Once you get to the new window, you will be shown all of your images and the option to delete the images that you no longer wish to keep.

Do of course let us know if you have any additional questions, or if you meant about removing images uploaded through your form and we would be happy to assist.

Thanks, this is fine to delete one at a time, is there any way to delete a group at once?

Unfortunately, there is no current option/way to delete group of images at once. This feature is currently not available. You will need to delete the images one at a time.
